Burning calories Question

How do you prepare for the rigorous physical requirements of high elevation adventure? Strength and endurance are key, but are only part of a more complex equation. How do you prepare for changes in altitude, exposure, diet, etc.? How do you mentally prepare? Learn from others and share what you know about training in advance for outdoor adventures.

You'll get more accurate results if you factor in heart rate which will allow you to use the Journal of Sports Science formula. (Or just use an HRM to do the Calorie estimation.) See for instance http://fitnowtraining.com/2012/01/formu ... es-burned/ .

Mike, You could actually gain calories if you hand the shovel to your wife, and then sit on the porch drinking a nice beverage.. :D

You can exercise all you want, but if your diet is out of whack, you won't have too much to show for it, especially during the holidays.


Not an a fitness expert but as a physiology teacher I think this needs a repeat. And exercise doesn't mean you earned he right to eat a little extra, like many people do. If calories burned exceeds calories absorbed you'll lose weight, it's physics more than physiology. Obviously there are different ways to go about it but cutting calories in tends to be the most efficient (but less fun)

Get a dog. Our border collie has to walk 5 miles a day or she goes berserk. I have actually been urban exploring with her. My goal is to walk every street in my unincorporated town. It has been quite amazing. We have a flock of wild turkeys and a number of roaming deer. And once a week we go to the river; urban but pretty nice - could almost guess that I was walking in Henry Coe park. Hard to not go walking when all I have to do is go out the door.

Mike,

Regarding walking uphill, this paper:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4306638/

shows that walking up a 7.5% incline at 2.9 mph has about twice the metabolic cost as walking 2.9mph on the flat.

The same as a 176 lb person. You burn about the same calories whether the weight is on your back or inside your skin.
BTW if you are 140lbs naked on the scale, do not forget to add the weight of your clothes and shoes. The pack is not the only weight your body is carrying.

Many now recommend calculating calories per mile instead of per hour -- more accurate. Per hour does not factor in speed (you burn more calories the faster you hike, but then you are covering the miles in less time). Using per mile is independent of speed.

Factoring in slope is more problematic. If it is round trip then ignore slope. The extra effort involved in going uphill is mostly offset by the lesser effort needed going downhill. Not completely offset, but close enough for quick estimates.

Of course, the old adage says the best exercise to lose weight is pushaways at the dinner table. ;)

Been wearing a fitbit lately and have found that drinking beer and reeling in fish lefthanded are great ways to get lots of steps in!
